BACKGROUND OF THE INVENTION 1. Field of the Invention The invention relates to a method for supplying the working places in machines (finished goods machines) for the production of flat textile products with at least one group of yarns. The invention further relates to an apparatus for carrying out the method and a method for producing a textile product with a set of parallel yarns for producing flat textile products.

The term "yarns" is to be understood to include monofilament yarns, yarns, twisted yarns, ribbons and the like as well as elastic materials. The term flat textile products shall be understood to include fabrics and knitwear, including snake-shaped and nets. The knitwear can be made on chain knitting machines or similar knitting machines.

It is known to use a chain bar to supply • finished goods machines with a multitude of parallel yarns. The known product 15 with a multitude of parallel yarns is in this case the yarn wound on the chain bar. The use of chain barriers causes disadvantages.

As soon as the chain bar is empty, it must be replaced with a new one, and the new chain bar chain yarns must be joined with the chain yarns from the previous chain bar while the finished machine is stopped. The connection requires a considerable amount of time, which is a major disadvantage of fast-working finished goods machines.

In rolling the warp yarns from the warp bar, while reducing the roll, the angle at which the warp yarns extend to the following guiding means, namely the tensioning roller. This changes the tension of the yarn during the roll bar roll. In order to counteract this disadvantage and to compensate for the change in the yarn tension, extensive mechanical and / or electronic measures are required.

Chain booms also require storage space and entail 30 transport costs.

Furthermore, it is known to supply finished goods machines with a plurality of parallel yarns directly from a bobbin frame, i.e. from a rack carrying a greater number of coils. The coil frame requires a lot of space and large investment costs. For each coil, an attachment point and a brake must be provided. For each of the yarns flowing from the coils, different oversteer is required. The coils themselves incur transportation costs and storage costs.

From US Patent No. 3,605,225 it is known to roll several yarns from chain barns and process them into a loose material with a 2

DK 157692B

extendable mesh. The looser is subjected to dyeing, texturing or other treatment, after which the weft yarn forming the retractable mesh rows is removed and the warp yarns are wound onto a boom or the like.

According to U.S. Patent No. 4,173,990, a loose (woven) product is manufactured for treating the warp yarns, e.g. by oxidation or carbonization. German Patent Publication No. 2,637,618 describes the manufacture of a woven band of meshes which is secured against stretching. German publication publication no.

No. 10,727,181 discloses the manufacture of a loose woven product of the same size as the same purpose as in the embodiment of U.S. Patent No. 3,605,225.

It is known from NO Patent Specification No. 133,739 to make a woven zipper and to close the edge with a stitch row.

The object of the invention is inter alia: to provide a method of the kind mentioned in the preamble, by which a ready-made group of parallel threads can be obtained without the need to use chain bar, coil racks or the like. The process according to the invention is peculiar to the properties set out in the characterizing part of claim 1.

The product manufactured is a woven product of low shoot density, hereinafter referred to as "loose goods". The yarn density must be seen in relation to the finished product to be manufactured by the loose goods.

Is the finished product e.g. in an extreme case, a woven item with 200 25 weft loops per piece. cm, already a woven item with 20 weft yarns per. cm could be described as a loose material. In most cases, however, the looser has a significantly lower shoot yarn density. The yarn loops must be woven in such a way that they can be pulled out again later in the form of an unbroken yarn. Only in this way can the extraction be made rationally and the yarn is again used. The same goes for two yarns introduced in the opposite direction.

After extracting the shot yarn or shot yarns, there is a group of parallel yarns which can then be immediately passed to one or more workplaces of finished goods machines. The shot yarns extracted from the solder 35 can be used again especially in finished goods production.

The use of chain bars is superfluous. The goods can easily be stored by letting it run neatly or unordered into magazines, preferably containers. A magazine can take up several tonnes 3

DK 157692B

detachable, thus replacing several chain booms with coiled chain yarn.

The goods can be transported at low cost. You do not need coil cores or the like, but you can use collapsible containers, cardboard boxes, grid boxes or similar containers that only take up little space on return.

The magazines can be placed in a company that manufactures finished goods far from the finished goods machines and / or the machines on which the goods are manufactured, e.g. in a separate storage room.

By means of guides, the goods can be transported over greater distances from a goods weaving machine to the magazines and / or from the magazines to the finished goods machines. A company that manufactures finished goods does not have to manufacture the goods themselves, but can have it delivered in containers, preferably in collapsible containers.

According to claim 2, multiple batches of yarn groups can be supplied to a single work site especially in such cases where the article to be manufactured has a wide width and e.g. must contain 4000 warp yarns, while the ransom must only be made with 500 warp yarns.

According to claim 3, a finished product can be made from yarns with different properties, in which loose goods with yarns with 20 different properties are used. Such properties may be provided by staining, shrinking, texturing and other processing.

After a chain bar has run out, the ends of the warp yarns can simply be connected to the ends of the warp yarns on the new warp bar after the machine is stopped. However, according to claim 5, the release article 25 in a container or the like can be connected to the release article located in another container while the finished product machine is still in operation. Thus, tying the yarns does not require stopping the machine. After the yarns from a container of loose material have been used up, the supply of the next 30 containers will continue without interruption of operation.

As mentioned, the invention also relates to an apparatus for supplying the workplaces in machines (finished goods machines) for the production of flat textile products with at least one group of yarns which have first formed warp yarns in a woven product (loose) having a ratio of 35 to normal woven. lasts low shoot yarn density and contains retractable shoot yarn loops. The apparatus according to the invention is peculiar to the properties of claim 6.

The invention further relates to a method for producing a textile product with a surface for machines for making surface 4

DK 157692B

textile products prepared group of parallel yarns. This method is set out in claims 7 and 8.

In the following, embodiments of the invention are explained with reference to the drawing. In the drawing: FIG. 1-4 in schematic form known in the art for weaving and knitting methods used in the manufacture of loose goods according to the invention; Fig. 5 is a perspective schematic view of a braking mechanism and a shotgun extraction apparatus disposed between a dispenser magazine and the work place of a finished machine; Fig. 6 is a view showing the joining of the ends of loose goods stored in two trays or containers; 7-9 pictures showing different ways of supplying loose goods to the workstations of finished goods machines, fig. 10 and 11 are views of the preparation of a loose material with 20 mesh rows formed by the yarn in two stages of manufacture, and FIGS. 12 and 13 are perspective views of individual parts of an answering machine weaving machine.

The loom is woven with a weaving machine, which will be described in greater detail later. The warp yarns to be woven can in some cases be pulled by single coils, e.g. is held on a bobbin frame. In this way, goods can be manufactured in a company that also manufactures finished goods. The looser may instead be woven from yarns leaving a yarn-making machine or yarn-making machine or from a rubber-spinning machine if elastic threads are desired. If a looser having more threads than a single one of the aforementioned machines can be produced, several such machines can be operated synchronously and together supply the necessary warp yarns. The redeemable item is filled in order or unordered in 35 magazines, preferably containers. A company that manufactures loose goods can supply the containers to companies that make finished goods. Instead, at least one finished goods weaving machine can set up a

DK 157692 B

Subtraction of yarns from bobbins weaves the looser and fills it in larger stationary placed on site. The trays can be placed at a considerable distance, partly from the looser weaving machines and partly from the finished goods machines, and the loose goods can be fed to the trays and from these to the finished goods machines over guides. If several adjacent magazines are filled one after the other, the goods do not need to be interrupted. If, from the last loaded magazine, the last manufactured end of the ransom is fed to a finished machine, this can be processed without interruption and without interconnection, the racks stored in several magazines one after another.

FIG. 1-4 show various possibilities for weaving loose bands by methods known per se. According to FIG. 1, weft yarns 3 are inserted into a crowd 1 of warp yarns from the left in such a way that the closed ends 3.1 of the yarn loops extend 1-2 cm beyond the right side of the belt. In the use of rough yarns, the loose band has sufficient stability to withstand unintentional pull-up. This method is suitable for shotgun densities with at least one shotgun loop per cm. product length.

20 According to FIG. 2, yarn loops 2 can be inserted from the left side and at the same location, yarn loops 5 can be introduced from the right side. Both weft loops are inserted into the same compartment by each insertion means. Closed ends 3.1 and 5.1 of weft loops project from both the right and left sides of the woven product.

25 This weaving method is suitable for loose goods with less weft yarn density than that of FIG. 1.

At shotgun densities down to 1 shotgun loop per 10 cm product length and possibly even smaller shot yarn densities are those in fig. 3 and 4, suitable weaving methods. According to FIG. 3, the looser is provided with a 30 mesh row 7 which, using a knitting needle 11, is formed by the shot yarn itself 9. In order to obtain particularly small shot yarn densities, the method can be used at both edges of the goods. Loop yarns introduced from left to right can be tied at the left edge of the item using a different row of stitches. The mask row can be pulled up 35 together with the yarn loops 3. If in fig. 3 removing the knitting needle 11, one can pull out the top shot yarn loop 3 to the left. Then comes the second highest, which also pulls up the associated mask. Thus, the erection must always be done from the last woven end.

FIG. 4 shows the preparation of a loose material using an auxiliary thread 13. Here, a mask row 7 'of the shot thread loop 3 and the auxiliary thread is formed. When pulling up, pull out the auxiliary thread 13 on one side and the yarn yarn 2 on the other side. During the use of two weft yarns, yarn loops can be introduced from the right and left, and the weft yarns located on each side of the product can be tied into each mesh row by means of auxiliary thread.

FIG. 5 shows an apparatus which is arranged between a magazine for the loose goods and the work place of a finished goods machine, which serves partly to tension the supply of the thread 1 of warp yarns and partly to pull out the shot yarn 2. FIG. 5 shows this in connection with the embodiment of FIG. 3 shows a looser in which a row of mesh 7 is woven using the yarn 2.

15 The release 17 is first directed to a braking mechanism having two rollers 31 and 32 which can be braked, as well as an auxiliary roller 33 which presses the release ring against the other two rollers. The finished machine pulls the warp yarns in the direction of arrow 50 so that the warp yarns are kept tensioned between the work site and the brake mechanism.

20 After leaving the braking mechanism, the loose belt runs over a stationary circle 35. Shortly thereafter, the shot yarn 2 is pulled, thereby pulling up the mesh row 7.

The yarn 2 is passed over a wire guide 55 to a yarn conveyor 57 known per se. This ensures that the yarn is pulled 25 at a certain speed. The pulling speed is adjusted to the length of the yarn loops 3 to be pulled up, as well as the stitches 58 and the rollers 31 and 32 of the rolls formed. The drawn shot yarn 2 is wound on a coil 60 and can be used again. Thus, the process does not increase material costs.

30 Loose items stored in two containers 61.62 can be linked to warp yarns, and this can be done while the loose goods from one magazine are fed to the finished goods machine. If the ransom has one or two mesh rows proceed as follows: The ransomers are filled in such a way that in addition to their last manufactured ends 17e, 17e ', their first manufactured ends 17a, 17a' are also available from the outside. The last manufactured end 17e of the loose article in the magazine 61 is fed to a braking mechanism 30 such as that of FIG. 5. The first manufactured end 17a of this loose material is joined to the last manufactured end 17e 'of the loose material in

DK 157692 B

7 the magazine 62, wherein warp yarns are joined with warp yarns and yarns with yarns and optionally auxiliary thread. When the magazine 61 is emptied, the end 17a carries the end 17e 'so that the magazine 62 is then emptied. This looser warp yarns pass through their 5 attachment locations 63 finished goods machine. If necessary, the piece of finished product containing the attachment points can be cut off later.

Empty magazines can either be replaced with filled ones or remain on site and refilled from a loader weaving machine.

FIG. 7-9 shows various options for supplying loose goods to the workstations of finished goods machines 64.

According to FIG. 7, a workstation 64 is supplied alternately from magazines 61.62 or from more than two magazines of loose material 17 over a thread extractor 27.

15 The braking mechanism 30, always located in front of the wire extractor 27, is not shown in FIG. 7-9.

According to claim 8, finished product 17 is fed from one of two magazines 61.62 to the yarn extractor 27. The group of yarns leaving the yarn extractor 27 is divided into three sections 1a, 1b and 20 1c. These sub-sections are routed to their respective workplaces 64a, 64b and 64c.

In the embodiment of FIG. 9 illustrates processed goods having different properties. Magazines 61, 62 contain movable goods 17a having a specific property. Magazines 65, 66 contain movable goods 17b having a different property. The properties can consist of different staining, 25 different fracture elongation numbers, i.e. notably different shrinkage of the chain yarns and more. Looser 17a runs into a yarn puller 27a and looser 17b into a yarn puller 27b.

The yarn group 1b exposed therein runs with its full width into the work place 64. The yarn group leaving the yarn extracting apparatus 27a is divided into two groups lal and la2. The two part groups form the edge chain yarns of the woven or knitted article or the like manufactured in the work place 64. The latter embodiment is of importance in the manufacture of automobile safety belts with tubular edges, where the edge chain yarns are more strongly shrunk than the chain yarns in the middle section.

By analogy, a work site 64 may be supplied to several yarn groups adjacent to each other, originating from different goods, and in this way, e.g. a product is manufactured which has several longitudinal color stripes.

FIG. Figs. 10-13 show the manufacture of a relatively narrow bulkhead on a needle-belt weaving machine. From a yarn-machining machine or a bobbin frame, a crowd 1 of warp yarns is fed to the needle-weaving machine. This one has a yarn insertion needle 70, a knitting needle 11 and a ridge 74. The knitting needle is slidable in the longitudinal direction of the belt between two end stitches 11 in the threads shown in FIG. 10 and 11.

A guide rod 76 extending connected to the machine and perpendicular to the belt plane in the form of a ceramic cylinder is placed close to the path of the knitting needle, i.e.. close behind the impact point 10 of the ride 74 77 (Fig. 11).

Located on the opposite side of the knitting needle is an angular lanyard retaining bracket 78 (Fig. 13) which is rotatable about a horizontal shaft 80. Figs. 13 shows this in its two endings 11. The yarn retaining bracket 78 has below its 15 spherical end 82 a lanyard 83 for securely guiding a 2.

Function;

In the embodiment shown in FIG. 10, the weft yarn 2.1 coming from the woven product runs around the lanyard on the weft yarn retainer 78, which occupies its upper position. The yarn insertion needle 70 has inserted a yarn loop 3 to the right, and the head 11.1 of the knitting needle 11 has just grasped the piece 2.2 of the yarn and begins to move in the direction of retraction (arrow direction 85.86). A shotgun loop 3.2 from the previous meshing is still on the shank of ll needle. During the protrusion 25 of the woven detachable 17, the knitting needle moves to the one shown in FIG. 11, thereby forming a mask which is turned off by the previously formed loop 3.2. A new loop 3.3 is formed, which is an extension of the shotgun loop 3. The knitting needle head 11.1 draws the loop 3.3 around the guide rod 76 in the direction of retraction 30 (arrow direction 85). The shotgun retention holder 78 has moved downward and released the shotgun 2.1, so that there is now a short shotgun loop 92 in the web. After the ride and the formation of a new subject, the work process is taken during which the loop 92 is tightened by the fast delivery of the item.

35 Larger-width loops are also manufactured during insertion of weft loops. In this case, however, other known means other than that of FIG. 10 and 11, insertion pins 70 are shown.
